Drive assembly for conversion system
A conversion system wherein a crankshaft drives the motion of the tooling assemblies within a number of lanes is provided. The crankshaft is structured to move the tooling assemblies associated with less than the total number of lanes. That is, for example, a four lane conversion press could include two crankshafts each actuating the tooling assemblies of two lanes. In an exemplary embodiment, each lane has a single associated crankshaft. The conversion system includes a multiple press drive assembly with a clutch/brake assembly and a flywheel assembly. The clutch/brake assembly is structured to suspend operation of the press units while the flywheel assembly stores energy in a flywheel. When operation of the press units is restarted, energy from the flywheel aids the motor in bringing the press units to an operating speed.
